LAMP-WICK REGULATOR.

Specification of Letters Patent.

Patented Oct. 18, 1921.

' Application filed February 19, 1921. Serial No. 446,233.

To all whom it may concern:

Be it known that I, J OSEPH C. ROBERT, J r., a citizen of the United States, and a resident of Agricultural College, in the county of Oktibbeha and State of Mississippi, have invented an Improvement in Lamp-Wick Regulators, of which the following is a specification.

My invention relates to devices for regu lating the wicks of oil lamps, stoves and the like, and it has for its principal object to provide a device by means of which such wicks may be quickly raised or lowered and adjusted with accuracy and preciseness to the exact point desired.

A further object of my invention is to simplify and cheapen the construction of devices for the purpose stated.

A still further object of my invention is to provide a device for regulating the wicks of oil lamps, oil stoves and the like which may, without previous adjustment or manipulation, be moved in either direction; that is, up or down, for the purpose of causing like up or'down movement of the wick.

Other objects and advantages of myinvention will be pointed out in the detailed description thereof which follows or will be apparent from such description.

In order that my invention may be readily understood and its practical advantages more fully appreciated, reference may be had to the accompanying drawing in which I have illustrated one form of a convenient embodiment thereof. However, it will be understood that the said invention is susceptible of embodiment in other forms of construction than that shown and that changes in the details thereof may be made within the scope of the claims without departing from said invention.

In the drawing:

Figure 1 is a central vertical section of a lamp provided with a device embodying my invention for regulating the lamp wick V Fig. 2 is a transverse sectional view taken along the line 2-2. of Fig. 1; and

Fig. 3 is a side elevation of the portion of the structure to which the device embodying my invention is applied.

Referring to the drawing: 1 designates the lamp bowl or oil reservoir having a central opening in its top, as indicated at 2, through which a cylinder or tube 3 extends,

the said tube being secured the edges of the opening 2 and the upper end thereof extending a dlstance above the top of the bowl 1 and the lower end thereof to a point a distance above the bottom of the said bowl, as shown in Fig. 1 of the drawing. 4 designates a central tube which constitutes a guide for the circular wick 5 of suitable fabric, such as cotton. The said wick is supported in the annular cylindrical space intermediate the tubes or cylinders 3 and 4. The top of the tube or cylinder 4 is flush with the top of the tube or cylinder 3, but the lower end of the tube or cylinder 4 extends through the lamp, as is common in such constructions.

The wick 5 is surrounded by a foraminous section of tubin 6 secured in any suitable manner to the said wick, as by riveting.

The outer cylinder or tube 3 is provided with elongated narrow openings 7 in diagonally disposed relation with respect to each other, as shown in the drawing, through which extend short pins 8 carried by the opposlte sides of a more or less oval shaped bail like member 9 (constituting a double armed lever) provided at a point midway between its opposite ends with a pivot portion 10 supported in a U-shaped bearing member 11 provlded at its ends with feet 12 which are secured by rivets 13 to the cylinder or tube 3. The portions of the opposite sides of the ad justable member 9 upon opposite sides of the p1ns'8 are spaced or separated from the cylinder or tube 3, as indicated in F ig. 2 of the drawing. The member 9 is provided at its opposite ends with outwardly extended parallel portions 14 spaced a short distance from each other as shown. These portions terminate in end projections 15 which extend toward each other. In addition to limiting the movement of the parallel portions 14 toward each other these end projections constitute a neat finish. For the purpose of adjusting the opposite sides of the member 9 toward and from each other, I have provided a right and left handed screw threaded rod 16, the opposite end portions of which are in screw threaded engagement withthe opposite parallel projecting end portions 14. The screw threaded rod 16 is provided at its center with a knurled wheel 17 by means of which it may be turned. By turning the screw threaded rod16 in one direction the opposite sides of the adjusting member 9 may be spread apart so as to withdraw the pins 8 from engagement with the wick 5 and the foraminous section of tubing 6, whereupon the said member 9 may be raised or lowered, and then by turning the threaded rod or screw 16 in the opposite direction the said pins 8 may be caused to reengage the foraminous tube section and wick at different points.

In order that the adjusting member 9 for raising and lowering the wick may be raised Or lowered to accomplish the purpose for which it is intended the pivot portion 10 thereof, when the said member is in horizontal position, as indicated in Figs. 1 and 3 of the drawing, should occupy a position a distance from the cylinder or tube3, so that when the said member is moved up and down about its pivot, the pins 8 traveling at such time in the narrow slots .7, the said pivot portion may slide back and forth in the U-shaped pivot bearing 11. As the ad j usting member 9 is moved either up or down from the horizontal position showniin the drawing, the pivot 10 thereof will slide in wardly toward the cylinder or tube 3.

. 2,0 designates a flame spreading device of known construction which is supported upon the upper end of the inner wick guiding tube or cylinder 4. 7

It will be apparent that by my invention I have provided a device which not only is simple and of durable construction, but Which maybe readily and quickly operated for the purpose of adjusting the wicks of oil lamps, stoves or the like either up or down as may be, desired.

Although I have shown the invention ap plied to a lamp having acircular wick. it will be understood that it is applicable to and may be employed in .connection with lamps having flat wicks.

Although not shown in the drawing, any suitable means may be provided upon the outer side of the upper end portion of the cylinder or tube 8 for supporting a lamp chimney.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is: 7

1. A wick adjusting device, comprising a double armed pivoted lever, the portion connecting the arms constituting the pivot, the said arms encircling the said wick and having-inwardly projecting pins to engage the latter, and a stationary bearing in which the said pivot is mounted.

2. A wick ad'ust1ngdev1ce, comprising a double armed pivoted lever, the portion connecting the'arms'con'stituting the pivot, the

said arms encircling the said wick and having meansadaptedto engage the latter, and an elongated bearing in which the said pivot is mounted, the length of said bearing extending transverselyot said wick.

3. A wick adjusting device, comprising a double armed pivoted lever, the portion connecting thearms constituting. the pivot, the

said arms encircling the said wick and hav ing inwardly extending pins in engagement with said wick, which, when the said lever is adjusted to different positions, causes corresponding adjustment of the said wick.

4. A wick adjusting device, comprising a double armed pivoted lever, the portion connecting the arms constituting a pivot, the said arms encircling the said wick and having means adapted to engage the latter, a stationary bearing in which the said pivot is mounted, and means foradjusting the said armstoward or from. each other.
